Commits: aaa73dd5 by Jinoh Kang at 2025-02-18T12:06:13+01:00 include: Fix ReadNoFence64 on i386.
64-bit volatile loads are not atomic on i386. Both i686-w64-mingw32-gcc and x86 MSVC splits 64-bit loads into a pair of load ops.
Fix this by using a FILD/FISTP pair, which is also used to implement C11 atomic_load() by i686-w64-mingw32-gcc.
